Direct air capture of CO2: the economics?

Direct Air Capture of CO2 (DAC) will cost around c$200/ton of CO2 abated, all in, and apples-to-apples with other technologies assessed by TSE. This data-file models out the economics of…

…DAC is only 140kWh/ton, and the world has simply not invented a process yet that is more than 5-10% thermodynamically efficient. We have modeled solutions from Carbon Engineering at c$300/ton…
…CCS or DAC. Today’s CCS and DAC processes are only 5-10% efficient, compared to their therodynamic minimum energy, and we increasingly wonder whether AI engines can help to develop sorbents…
…place next on the cost curve and could each have GTpa scale. Power stations place next, at $60-100/ton. DAC is conceptually attractive, as the only carbon negative technology, but if…
…than, say, Carbon Engineering. The main innovation visible in Climeworks’ patents is a DAC plant with optimized air flow, passing CO2 through layers of fabric housing CO2-adsorbing materials. This is…

…of magnitude). This is one of the challenges for DAC. Most promisingly, some CO2 is already purely concentrated (e.g., after pre-treating natural gas before LNG liquefaction; or after separating out…
